ABSTRACTBackgroundBisphenol A (BPA) is a high-production volume chemical that is commonly used to manufacture consumer and medical-grade plastic products. Due to its ubiquity, the general population can incur daily environmental exposure to BPA, while heightened BPA exposure has been reported in intensive care patients and industrial workers. Due to health concerns, structural analogues are being explored as replacements for BPA.ObjectiveThis study aimed to examine the direct nongenomic effects of BPA on cardiac electrophysiology and compare its safety profile to recently developed alternatives, including BPS (bisphenol S) and BPF (bisphenol F).MethodsWhole-cell voltage-clamp recordings were performed on cell lines transfected with Nav1.5, hERG, or Cav1.2. Results of single channel experiments were validated by conducting electrophysiology studies on human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CM) and intact, whole heart preparations.ResultsOf the chemicals tested, BPA was the most potent inhibitor of both fast (INa-P) and late (INa-L) sodium channel (IC50 = 55.3 and 23.6 μM, respectively), L-type calcium channel (IC50 = 30.8 μM) and hERG channel current (IC50 = 127 μM). The inhibitory effects of BPA and BPF on L-type calcium channels were supported by microelectrode array recordings, which revealed shortening of the extracellular field potential (akin to QT interval). Further, BPA and BPF exposure impaired atrioventricular conduction in intact, whole heart experiments. BPS did not alter any of the cardiac electrophysiology parameters tested.DiscussionResults of this study demonstrate that BPA and BPF exert an immediate inhibitory effect on cardiac ion channels, and that BPS may be a safer alternative. Intracellular signaling or genomic effects of bisphenol analogues were not investigated; therefore, additional mechanistic studies are necessary to fully elucidate the safety profile of bisphenol analogues on the heart.

Bisphenol Analogues

In recent years, bisphenol analogues such as bisphenol S (BPS) have come to replace bisphenol A in food packaging and food containers, since bisphenol A (BPA) has been shown to leach into food and water, causing numerous negative health effects. Unfortunately, little or no research was done to determine the safety of these BPA-free products before they were marketed to the public as a healthier alternative. The latest studies have shown that some of these bisphenol analogues may be even more harmful than the original BPA in some situations. This article used a literature survey to investigate the bisphenol analogue BPS and compare it to BPA and other analogues with regards to increased obesity, metabolic disorders, cancer, and reproductive defects; among others. It was found that BPS works via different pathways than does BPA while causing equivalent obesogenic effects, such as activating preadipocytes, and that BPS was correlated with metabolic disorders, such as gestational diabetes, that BPA was not correlated with. BPS was also shown to be more toxic to the reproductive system than BPA and was shown to hormonally promote certain breast cancers at the same rate as BPA. Therefore, a strong argument may be made to regulate BPS in exactly the same manner as BPA.
